Many people consider fish (or JUST consuming fish) a good choice from an ethical, health and environmental standpoint. They believe fish are healthy to eat, don’t feel pain or complex emotion and don’t take a toll on the environment. So the perfect meat choice for someone who’s not ready to go completely vegetarian or vegan, right?
This assumption is widespread, but couldn’t be farther from the truth.
(Mark Bekoff said it first, Fish are not mere streams of readily available unfeeling protein.)
The first argument that may lead you to believe that fish do not feel pain, might be the absence of a neocortex. This is an inappropriate anatomical comparison- we can’t judge another beings ability to process pain because it differs from ours any more than a butterfly can believe humans can’t taste because we do it with our mouths and not feet.
“Evidence from neuroanatomy, neurophysiology, and neuropsychology suggests that
the experience of feelings in humans does not depend exclusively on structures of the cerebral
cortex. It does not seem warranted to deny the possibility of feeling in animals… We do not see any evidence in favor of the idea that the engendering of feelings in humans would be confined to the cerebral cortex. On the contrary, based on anatomical and physiological evidence, subcortical structures and even the peripheral and enteric nervous systems appear to make important contributions to the experience of feelings.”

In fact; a study conducted by Prof. Joseph Garner and Doctoral student Janicke Nordgreen at Purdue University proved goldfish feel pain and discomfort beyond instinctive reflex.
Essentially, in this not-so-pretty experiment; Garner showed that fish put in painful situations reacted differently to fish who were not. Goldfish injected with a saline solution were studied alongside goldfish injected with a pain blocking morphine solution and both were put in painful levels of heat (with safeguards to not destroy tissue).
Although both fish originally responded the same, wriggling at the same temperature; only the fish without the pain blockers experienced a fear response. They displayed wariness of the new object, as well as anxiety. This matches up with earlier observations of fish injected with painful solutions who would rock back and forth on the tank floor, rub their lips against the glass a and stop eating. Both groups of fish injected with pain blockers experienced no such response.
Not only are they sentient in a way that shows they can feel pain, fish are actually very smart and can remember quite far! Not the 3 minutes you might have been told is the maximum time frame they can remember.
In fact, fish have been proven to remember for up to at least 5 months.
They recognize their tanks layouts and will detect a change in setup or a new item.
This goldfish won a world record for being able to remember and perform six tricks such as;
- Eat from hand
- Swim through loop
- Swim through tunnel
- Play football
- Play fetch
There’s Albert Einstein playing limbo!
And there are many others who have been able to teach their fish tricks.
The second misconception is that fish is healthy. While it may be more healthy than other types of meat, I wouldn’t consider it a health food even if we’re ignoring it’s high mercury content. To borrow a few points from my general article on the health affects of meat consumption;
- The feeding of infected cow and sheep brains is still legal in the USA. Sources: NCBI; 1, 2.
- Even when meat consumption is reduced to only fish, cancer causing IGF-1 levels remain relatively the same. Source: Cancer Epidemiology, Biomakers & Prevention.
- PCB’s (Polychlorinated Biphenyls) i.e Instrustrial toxic waste, still found in the environment can be found in fish 1000x higher in levels of PCB’s then the water they live in. They cause skin problems, neurobehavioral and liver damage and cancer in both animals and humans. Source: Agency for Toxic Substances and Disease Registry.
- PhIP (found in fish) stimulates breast cancer cells, also making them invade healthy cells more than estrogen itself even when PhIP is in low concentrations. Source: NCBI
- Fish, regardless how it’s cooked, seems to be directly related to endometrial cancer risk. Source: NCBI
So you’d do better replacing your fish with vegan versions of seafood; even if you don’t think fish are friends!
If you’re interested in saving our planet, this might be the most compelling reason to cut fish out of your diet; the ocean is suffering immensely due largely to overfishing. While it may be easy to dismiss this as “just” a cause of overfishing and not fish consumption itself; we must remember that we cannot feed 7 billion humans the sadly still recommended 3+ servings of fish a week without overfishing. There is too much demand to meet that supply.
- 90% of all large fish have disappeared since we introduced industrial fishing techniques in the 1950’s.
- 38.5 tons of sea life (40% of all catches) is discarded; this is called by catch.
- “Sustainable” fishing isn’t all that sustainable.
- Jellyfish population is steadily increasing and the ocean could soon become egregiously overpopulated with them, which would be catastrophic.
- 2 trillion sea animals are killed annually.
- The ocean could be completely empty by 2048.
- Fisheries averaged $27 billion in subsidies in 2003.

Worried about Omega-3’s? No problem!
- Chia seeds
- Flax seeds
- Brussels sprouts
- Algal oil (EPA & DHA)
- Hemp seeds
- Perilla oil
Experts say as long as you get enough ALA, you don’t have to worry about EPA and DHA from non vegan sources. And if that’s not enough to ease your mind, there’s nothing wrong with supplementing; after all, meat eaters supplement more than vegans and vegetarians combined.
If this article makes you want to go vegan, try it! Good luck ❤️🐟
